Isnt a mBTC = .001, so 10 mBTC = .01 BTC

and .01 * $522 = $5.22 per unit of 32 GH  so it would be around .16 USD per GH.  Which seems somewhat unbelievable so i am sure i made some incredibly stupid error somewhere in there.

and about 1.3W/GH?  Not super power efficient - this can't be 28 nm tech can it?

Of course the website says out of stock so all this is moot.  At the price they posted, i would order some for giggles..
